Why does i get the blank response while getting case template by group id which i created?

I have created Group and using the id of the group i tried to fetch the Case Template. But i am getting blank response in pilot environment. I have created 2 custom fields as well. But still the response is same. What does i am missing?

Using your code I got successful result. Once you can run the main program WorldCheckApiMain you can get menu option in your screen.For case template you can press 3 and you will get the result.Attached the screenshot in my local environment.If you need will do webex.

Can you please run the option 1 Get Top Level Groups in java and send me the screenshot.Use one of them groupId.I think your groupId is wrong.I saw your code and you are using my credentials and in this credentials there is no groupId whatever you are using.

If you want to get your own groupId you can use your own credentials.You are using my Apikey and SecretKey. That's why in java code you are not getting your groupId. Please can you use your own credentials if you have and then run the java code.The groupId you are using it's not exists in this using java code credentials .That's why you are getting 404 error.Please use correct groupId which is available in option 1 Get Top Level Groups.
